WAYNE H. M GLADE RONALD C. KAMP ATTORNEY United States Patent 3,288,530 TRUCK Wayne H. McGlade, Peoria, Ill., assignor to LeTourneau- Westinghouse Company, Peoria, Ill., a corporation of Illinois Filed Nov. 16, 1964, Ser. No. 411,501 3 Claims. (Cl. 298-17) The present invention relates generally to trucks, and more particularly, to trucks for hauling a hot material.

The slag resulting from a large steel mill operation comprises a considerable volume. In order to permit efficient operation of the mill such slag must be collected quickly and disposed of before it has an opportunity to solidify. In the past, railroad cars, which were designed specifiaclly for this purpose, were utilized. However, rail transportation is slow and removal of the material from the cars is often difficult and cumbersome.

It is, therefore, an object of the present invention to provide a truck having a means for containing, carrying and dumping slag in its molten condition, and which will have a prolonged life in an environment of high temperatures.

Other objects and many of the attendant advantages of the present invention will become more readily apparent from a perusal of the following specification and the accompanying drawings, wherein;

FIG. 1 is a perspective view, with portions broken away, of a truck embodying the present invention, and

FIG. 2 is a cross-sectional view, in side elevation, of the truck of FIG. 1 with portions shown in dotted lines.

Referring now in detail to the drawings, there is shown a truck, indicated generally as 10, having an engine, not shown, and a dump body 12 which is pivotally mounted on the truck frame 14 for rearward dumping. An inner liner 16 is secured to the dump body 12. A plurality of baffles 17 are securely and intimately afiixed to the outer surface of the liner 16. These baffles 18 serve to space the liner from, and support the liner on, the body. In addition, the baffies, because of their intimate contact with the liner, function as cooling fins to conduct heat away from the liner. In a manner to be explained hereinafter, the baffles 18 direct the flow of air between the liner 16 and the body 12. A fan 18 is driven by a motor 20, which may be electric or hydraulic, or alternatively, the fan may be driven directly by a mechanical linkage from the truck engine. As best shown in FIG. 2, the fan is mounted on the truck in a duct 22 which communicates, through an opening 24 in the body 12 when the body is in its lowered position, with the space between the liner 16 and the body 12. Air is drawn in through the duct by the fan 18 and is forced into the space between the liner and the body where it is directed by the baffles 17 throughout the said space. The liner 16 extends beyond the body 12 and the air is permitted to exhaust from the resulting clearance therebetween. A flexible seal 26 is secured to the rearward end of the duct 22 and sealingly engages the body 12 in its lowered position. This seal 26 permits efiicient transfer of air from the duct 22 to the space between the body 12 and the liner 16 through the opening 24.

Thus, it can be seen that the liner 16 will be cooled continuously, whenever the body 12 is in its lowered position, because of the circulation of air through the spaces therebetween and because the plurality of bafiles conduct the heat from the liner 16 and present a large area for 3,288,530 Patented Nov. 29, 1966 transferring the heat to moving air. In addition, these bafiles 17 strengthen the liner 16 and provide support, by resting on the body 12, for the weight of the hot material contained therein. In accomplishing these esults, the bafiles effectively isolate the remaining portion of the truck 10, including the body 12, from the intense heat of the molten slag.

Further, there is no need to incorporate an expensive valve or switch to stop the fan 18 as the slag is dumped, in order to prevent damage to surrounding property or injury to adjacent personnel. Such a function is achieved by the dumping of the body 12, since the opening 24 therein moves away from the duct 22 and the air from the fan 18 is no longer directed into the spaces between the body and liner.

When the liner has been eroded or otherwise rendered useless by the hot material, it is a relatively easy operation to remove the old liner and install a new one. Such ease of replacement can be accomplished because the liner is attached to the body, by bolts, welds or any other Well-known fastening means, at only a few points, there being no positive physical connection between the baflles 17 and the body 12.

While there is in this application specifically described one form which the invention may assume in practice, it will be understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.

What is claimed is:

1. In a truck for hauling hot materials wherein the truck has an engine and a dump body including a bottom, side walls and an end wall, the body being mounted on said truck for pivotal movement between a raised position and a lowered position, the improvement comprising:

a liner having a shape complementary to said body and positionable therein,

a plurality of bafiies intimately secured to the liner for spacing the liner from and supporting the liner on said body,

fastening means securing the liner at selected points only to said body,

a fan mounted on said truck,

drive means for rotating the fan,

a duct for receiving the output from the fan and having an open end,

and said body having an opening therein,

the opening being located and shaped to encompass the open end when said body is in its lowered position,

whereby air is circulated between the liner and said body whenever said body is in its lowered position.

2. In a truck according to claim 1 and further comprising a flexible seal attached to the open end of the duct and engagable with said body when in its lowered position whereby air is efficiently transferred from the duct to the space between the liner and said body.

3. In a truck for hauling hot material such as slag wherein the truck has a dump body including a bottom, side walls, and an end wall, said body being mounted on said truck for pivotal movement between a raised position and a lowered position, the improvement comprising:

a removable liner including a bottom, side walls, and an end wall, said liner having a shape complementary to said body and positioned therein,

baifie. means heat conductively and fixedly secured to said liner bottom, side walls and end walls, said bafile means supporting the liner in spaced relation to said body by abutment against said body,

fastening means securing the liner at selected points only to said body,

a fan associated with said body,

drive means for rotating said fan,

a duct for receiving the output from the fan,

and said body having an opening therein in fluid communication with said duct for directing the output of said fan in the space between said body and said liner and about said bafiie means,

whereby removal of said fastening means permits simul taneous removal of said liner and said baffle means as a unit.
